THIS Is How Much Cheaper Aldi Is Compared To Coles

Woolworths shoppers are being slugged an extra 12 per cent and Coles shoppers an extra 14 percent on branded products such as Coke, Tim Tams and Weet-Bix compared to the prices set by Aldi.

Aldi says it aims to be 20 to 25 percent cheaper on a basket of groceries compared to Woolworths and Coles and it does so by selling almost exclusively home-brand products and having less staff.

However, as Aldi expands, it is increasing its range to draw more customers in but is expected that will mean lower profits.

The Age have undertaken a study in Aldi, Woolworths and Coles supermarkets on Friday across 125 branded products.

Of these, just 36 were sold in the same size at Woolworths and Coles supermarkets nearby. The list includes big brands such as chocolate makers Nestle and Mars, lolly brand Allens, Heinz and Johnson & Johnson.

If a shopper bought all 36 items from Aldi, they would pay $113.25.

If they bought all 36 items from Woolworths, they would pay $126.67.

The same items being bought from Coles would see the customer paying $129.50.

That means that if somebody were to undertake the same shop at Aldi, every week, for 52 weeks of the year at Aldi, they would save $688.48 compared to Woolworths.
